ScienceDaily: Eat Less To Live Longer: Calorie Restriction Linked To Long Healthy Lives

For nearly 70 years scientists have known that caloric restriction prolongs life. In everything from yeast to primates, a significant decrease in calories can extend lifespan by as much as one-third. But getting under the hood of the molecular machinery that drives this longevity has remained elusive. Researchers have now discovered two genes in mammalian cells that act as gatekeepers for cellular longevity. When cells experience certain kinds of stress, such as caloric restriction, these genes rev up and help protect cells from diseases of aging. Saved By: MattBirt | View Details | Give Thanks
